Nothing adds luxury and elegance to a bathroom like a solid surface bathroom countertop made of granite, quartz or marble. The expense of the material might make you think that only an expert would be able to install it, but the truth is that you can install sold surface countertops yourself at a fraction of the cost. Just follow these steps.

Step 1 - Measure

Carefully measure the area for the new countertop. Account for a 1-inch overhang, as well as for the size of the sink.

Step 2 - Purchase Materials

Think carefully about what kind of stone you want to use in your bathroom. Experts recommend marble over granite, which requires expertise to handle. Visit to your local hardware store examine the options. Marble comes in a variety of colors and patterns. Bring your measurements with you and have the store cut the stone to size. You can also get a separate piece of the same material cut for the backsplash that will go on the wall behind the sink.

Step 3 - Prepare for Installation

Remove the old sink and countertop. Remember to shut off the water valve to prevent a flood. Disconnect the sink and faucet from the plumbing. Then use a utility knife to pry the caulk from the existing sink and walls. Gently lift the sink and countertop unit, taking care not to nick or scratch the walls or vanity. Most units are integrative so that you can pull the countertop and sink out as a single object.

Step 4 - Install the Counter and Backsplash

Ensure that all the plumbing fixtures are properly connected before installing the new countertop. Apply caulk to the vanity, lift the countertop over the vanity, and press it firmly into place. Solid surface countertops are heavier than formica or other synthetic materials, so you will probably need an extra set of hands to help you lift and hold the unit in place during this step. Apply caulk to the back of the backsplash and fix it to the wall. Slide the sink into place in the countertop opening.

Step 5 - Attach the Sink

Insert the sink. Remember to caulk around the edge of the sink to prevent leaks. Reconnect the pipes under the sink. Tighten the joints as firmly as possible and finally insert the pop-up drain. Turn the water valve back on and give the whole system a test run.
